Specification of Letters Patent.

Patented Jan. 9, 1912,.

` Application led April 15, 1911. Serial No. 621,238.

To all whom it may concern:

Be it known that I, JOHN C. BARBER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Gar-Trucks; and I dohereby-declare the following to be a full, clear, and eXactdescriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use ethe same.

My invention relates to car trucks of the general type disclosed in mynumerous prior patents wherein provision is made for limited lateralmotion of the car body in respect to the supporting trucks inaddition tothe customary swiveling or radial motion, and especially wherein boththe lateral and radial motions are taken on anti-friction bearingrollers.

More specifically stated, the present invention is directed to theimprovement of the general arrangement of the lateral motion and radialmotion devices disclosed and claimed in the patent to Lake and Deverell,798,350, of date August 29, 1905, and in my prior Patents 863,012 ofdate August 13,

1907, and 875,565 of date December 31, 1907.

The present 4invention isdirected to an improvement on or modificationof the several constructions disclosed and claimed in the said patentsabove identified and the invention, generally stated, consists of thenovel devices and combinations of devices` hereinafter described anddened Vin the' claims.

In the accompanying drawings, whichv illustrate the improved truck, likecharacters indicate like parts throughout the several views.

Referring tothe drawings, Figure 1 is a view in side elevation, withsome parts broken away, with some parts sectioned and;`

with some parts shown in diagram, ,some

parts being entirely removed, showlngvone So far as the broad featuresof the inven tion are concerned, the side frames of the truck may beeither cast or of the arch bar type, but, as shown, it is of the lattertype and comprises a top arch bar 1, a bottom arch bar 2 and a bottomtie bar 3, which parts at their ends are secured in the customary or anysuitable way, to journal boxes, not shown. The bolster columns 4 arecast structures interposed between the intermediate portion of the archbars 1 and 2. The flanged upper ends of these bolster columns are shownas riveted to the top arch bar 1 and at their lower ends they are shownas provided with angular bases 5 having depending sleeves 6. The bases 5rest upon the end portions of inverted channel-shaped saddle plates 7vand their sleeves 6 are mounted in seats formed in the said saddleplates. The depending fianges of the saddle plates 7 embrace theintermediate lower portions of the bars 2 'and 3, and in lieu of longcolumn bolts, short nutted bolts 8 are passed through the bases 5 andtheir sleeves 6 and through perforations in the said bars 2 and 3. Theheads of the bolts 8 are preferably seated on top of the column bases 5andthe said columns immediately above the same are cut away, so that thesaid bolts, when their nuts are removed, may be easily 4lifted out ofworking positions or applied in plates 7, serve to hold positionedcoiled bolster supporting springs 11.

The truck wheels 12 are diagrammatically "shown only in Fig. 1. It will,of course, be 4understood that their axles may be journaled in thejournal boxes in the customary way.

The car body or platform 13, in accordance with my invention disclosedand vbroadly claimed in my cospending application S. N. 619,216, filedof date April the 6th, 1911, and entitled Car construction;7

isV provided with longitudinally extended side sills 111 that arelocated directly over the rtruck side fra-mes. These side sills 14, asshownare I-beam structures made up of vertical plates and reverselyarranged pair of angle'bars, but this has nothing tol do with thepresent invention, but is a feature specifically claimed in myco-pending application S. N. 621,239, led of date April the 15th, 1911,and entitled Underframe structure for cars.

The car body bolsters 15'which, as shown, are formed by heavy metalchannel beams, have end portions 15a of reduced' vertical dimensionsthat are extended directly under and are rigidly secured to the endportions of the side sills 14. Bearing brackets 16 are :riveted orotherwise rigidly secured both to the body bolsters 15 and to the lowerflanges of the side sills 14. These bearing brackets 16 are providedwith depending legs that straddle or embrace the upper arch bars 1 withsuflicient clearance to permit the required lateral motion of the carbody in respect to the truck or as will hereinafter more clearly appear.

The bolster supporting springs 11, as shown, are arranged in groups offour and they directly support combined spring caps and ro-ller bases 17that are guided for vertical movements, butare held against horizontalmovements, by the parallel inner faces of the bolster columns 4. Thetruck bolster 18, which as shown and preferred is ,in the form of metalI-beam, is extended between the bolster columns 4 and has riveted orotherwise rigidly secured to the under surface of its horizontal web andbetween .its depending flanges, a roller cap 19 between which and thecooperating combined `spring caps and roller bases 17, lateral moties,the roller caps 19 are shown as provided with depending stop lugs 21thatv engage with the inner edges of the combined spring caps and rollerbases 17 and limit the endwise movements of the 4truck bolstertransversely of the truck. The elements 17, 19 and 20 constitute theanti-friction lateral motion devices of the truck.

At their-central portions, the body bolster 15 Aand truck bolster 18 arepivotally connected, as shown, by a depending hub 22 on the former andby a coperating flange bearing collar 23 on the latter. No part of theweight of the load is carried by or transmitted through the saidelements 22 and 23.

Secured on the uppersurface ofthe web of the truck bolster 18 directlyabove the roller caps 19 are roller bases 24 upon which @are seatedbearing rollers 25. A roller vcap 2,6 is supported upon the -rollers 25and the lower ends or feet of the depending legs of the so-calledbearing brackets 16 are seated in depressions formed in the said rollercaps and, in turn, are provided with notches 27 that receive upwardprojections 28 of the said roller caps. In this way, the roller caps 26are normally locked to the legs of the bearing brackets 16, so that theymust move therewith under radial or pivotal ,movements of the truck inrespect to the car body. The said elements 24, 25 and 26 constitute theside bearings or radial motion antifriction devices of the truckV and,hence, the rollers 25 will extend longitudinally of the truck bolster18, or, preferably, in a direction radiating from the axis of thepivotal connection 22-23.

The numeral 29 indicates small bolster end caps which, as shown, aresecured -to depending flanges of the roller caps 19, by short nuttedbolts 30, and are provided with lips 81that overlap the ends of thehorizontal web of the said bolster.

The truck bolster 15 moves transversely of the truck and, hence, movesendwise through the truck side frames. It is of less width than thedistance between the coperating bolster columns 4 and is provided withchang plates 32,'best shown in Fig. 4, by reference to which 'it will beseen that the intermediate portions of the chafing plates are offsetfrom the side of the bolster and that their ends are bent inward andriveted to the fianges of the said bolster. Also, as shown, the bolstercolumns 4 are provided with projecting brake hanger arms 38 shown onlyat the right in Fig. 2.

In the drawings, the radial motion of the side bearing rollers 25 areshown as held properly spaced by a cage or roller spacing deviceindicated as an entirety by the numeral 34. This roller spacing device,however, forms no part of the present invention, but is disclosed andclaimed in my co-pending application S. N. 621,240, filed April the15th, 1911, and entitled Roller bearing.

From the foregoing description and especially the drawings, thefollowing facts are made evident That the truck bolster moves endwisewith the body bolster transversely of the truck, or in other words,partakes of the lateral motion car body in respect to the truck, but iscapable of radial or pivotal lmakes it practicable to place thebodybolsters below the side sills of the car and, in doing so, does notraise the car platform .or

-body too high. That the connection between the roller cap of the radialbearingV device, and the body bolsteror sidesillspr both, lis made inavery .simple and efcient'manner dimensions since it is embraced by thelegs of the bearing brackets 16. What I claim is:

l. In a car truck, the combination with truck side frames having topcompression members, of a truck bolster and a body bolster pivotallyconnected for radial movements and for simultaneous endwise move-- mentstransversely of the truck, anti-friction lateral motion bearingssupporting said truck bolster from said truck side frames, and radialmotion anti-friction side bearings located within said side frames belowthe top compression members thereof and supporting said body bolsterfrom said truck bolster.

2. In a car truck, the combination with truck side frames having toparch bars, of a truck bolster and a body bolster pivotally connected forradial movements and for simultaneous endwise movements transversely ofthe truck anti-friction lateral motion bearings supporting said truckbolster from said truck side frames, radial motion anti-fric'- tion sidebearings located within said side frames below the top arch barsthereof, laterally spaced bearing legs secured to said body bolster,straddling the said top arch bars with clearance and supporting saidbody bolster from said side bearings.

3. In a car truck, the combination with truck side frames, of a truckbolster and a body bolster pivotally connected for radial movements andfor simultaneous endwise. movements transversely of the truck,antifriction lateral motion roller bearing devices spring supported fromsaid side frames and supporting said truck bolster, and radial motionanti-friction roller side bearings located within said side framesbello-w the top arch bars thereof andisupporting said body bolster fromsaid truck bolster.

4. In a car truck, the combination with truck side frames, of a bodybolster connected to said truck for radial movements, anti-frictionlateral motion and anti-friction radial motion bearing devicessupporting said body bolster from said truck side frames, and a car bodyhaving main side sills resting on and secured to said body bolster andlocated directly above said truck side frames.

5. In a car truck, the combination with truck side frames, of a bodybolster connected to said truck for radial movements, anti-frictionlateral motion and anti-friction radial motion side bearings andcooperating supporting springs supporting said body bolster from saidtruck side frames, anda car body having main side sills resting on andsecured to said body bolster and located directly above said truck sideframes.

6. In a car truck, the combination with truck side frames having toparch bars, of a truck and a body bolster pivotally connected for radialmovements and for simultaneo-us endwise movements transversely of thetruck, anti-friction lateral motion roller bearings supporting saidtruck bolster from said side frames, radial motion roller side bea-ringssupported on said truck bolster below the top arch bars of said sideframes, and bearing brackets rigidly secured to said truck bolster andhaving depending legs embracing the top arch bar of said side frameswith clearance and detachably seated on the said side bearings.

7. A truck bolster having changcplates for engagement with the truckcolumns, formed by iat plates having their body portions offset fromsaid bolster and having their end portions bent laterally and rigidlysecured to the sides of the end portions of said bolster.

In testimony whereof I aiiiX my signature in presence of two witnesses.
